“International migrants are sending more than $500 billion back to family members each year, almost triple the figure since 2000, providing a major economic boost to less-affluent nations, a Pew Research Center study shows. A rising share of migrants live in high-income countries, including the U.S., by far the most common destination, according to the report released yesterday. The U.S. has a fifth of the world’s migrants, up from almost a sixth in 1990. It’s also the largest source of payments, sending $123.3 billion in 2012, the Pew analysis of World Bank data shows. The U.S. and Russia easily remain the top two destinations, while Germany has risen to third from sixth in 1990.”
